now i'm making a 8 inch full ranger unit, the High frequency will more than 22000HZ, lower frequency reach 100HZ,blow 100HZ giveup,user can add a sub woofer or use Labyrinth box,because the full ranger can't be Perfect,like lowther's Mentality . 
Chinese,
Close. I will mark up your diagram for dimensions preferred and one more I must have. This will take a small amount of time.
Would you trade expert information on paper technology? I do not want to make your cone, I have other ideas and other projects but paper is only made in factory in USA, or by hobby people for celebration cards. Speaker cone makers are very secretive and do not want to have my expert ability in trade.

It's very very difficult to made this cone,and only can made by Human hand, Machine can't do it, 14 inch only 17g with Very good Rigidity and Suitable Damping,it is Secret.
Chinese,
I do not need to know your secret of damping. Funny looking dots on surface will take care of that. I only want to know how to make cones by hand, not with machine. Want to make different, very shallow depth and smaller diameter. Maybe only one step, not three cone steps like yours.
Trade my knowledge for yours, I keep some secrets for you to discover if you need to know them, you keep some secrets I do not need to know.

Much more interesting to me. I prefer to make conventional cone without ribs, but with light weight paper, made by hand.
I have a conic section completed to your dimensions. Do you have a program that will read Auto Cad DWG or DXF file format? If not I will send a full size JPG to you via email tomorrow. It will take some time to convert and do a good job.

if not three cone steps,maybe the High frequency can't reach 20000HZ, because each steps are Mutually cooperates😀
Chinese,
I will put it into jpeg format tomorrow. Will your email address from here be best or do you want to send me a direct email and I will send direct back to you?
The pattern is called EnABL here in the USA, just so you know. I am not worried about 20 k Hz as the pattern will allow cone to produce this frequency and down to below piston point also.
Maybe steps will be needed. I would need to experiment, but do not have the skill. Can you transfer enough knowledge with pictures and simple explanations? It would be better if we could work together but the pacific ocean does not get smaller.

the most powerful knowledge is Creation no Follows,you need Do It Youself. I will Establish another "lowther" or "AER" in Future.
Hello,
cool, very cool, congratulation.
Yes to do it better as Lowther is possible,
cheaper as AER also.
My question:
works it also as a bending wave transductor, like DDD
and Manger?
Did you make measurements to find the 2kHz problem.
Is it more a problem of membran contur, or a partial
effect of the membran itself?

i will solve the problem, the frequency line not mean the result,if you saw lowther unit frequency line, you will never buy it,but it's sounds very nice, why? something we can't explain.
You are right, don´t believe in frequency lines.
What is about step response?
Bending wave ?
The 2 kHZ problem might be a problem of the
dimension of the membran construction and or
mechanical membran lack, search for this part
of the membran, thin second adhesive might help.
good luck

Interesting and serious 😎 with your chinese paper art, it looks like you can do almost anything you like

Very inventive but I am also kind of a conservative guy.... look at the shape of a violin, havent been changed fore hundreds of years and cant be improved
I would like to see a small membrane made with integrated surround, to be used as mid/tweeter - made with your paper artwork
Or the "ringradiator" like you show in the picture, could be interesting in a small version.... without the surround

chinese: so light and big cone ....Impressive. I hope i will see moro of your creation in the future.
the steps is very Important,when it work in High frequency i hope only the first inside cone working,when in low frequency the whole cone working, it is my design Mentality and it seems working well.
i can do almost any size of full ranger unit what i want. i also done an Earphone before,it's a small full ranger speaker.
